Actionscript:
-
var connect:Function = function(xp:Number, yp:Number, col:uint=0):Function{
-
graphics.lineStyle(0,col);
-
graphics.moveTo(xp, yp);
-
var line:Function = function(xp:Number, yp:Number):Function{
-
graphics.lineTo(xp, yp);
-
return line;
-
}
-
return line;
-
}
-
-
// draw a triangle
-
connect(200,100)(300,300)(100,300)(200, 100);
-
-
// draw a box
-
connect(100,100, 0xFF0000)(150,100)(150,150)(100, 150)(100,100);
This is one of those techniques that I never really get tired of. It's pretty useless, but fun to play around with every now and then. This draws the somewhat boring looking picture below:
[EDIT]
A few people pointed out that this could be simplified with arguments.callee... So here is an example... it does the same thing as the original code...
Actionscript:
-
var connect:Function = function(xp:Number, yp:Number, col:uint=0):Function{
-
graphics.lineStyle(0,col);
-
graphics.moveTo(xp, yp);
-
return function(xp:Number, yp:Number):Function{
-
graphics.lineTo(xp, yp);
-
return arguments.callee;
-
}
-
}

Note: This snippet requires the QuickBox2D library
This snippet shows an easy way to get at the settings for Box2D's debug renderer.
Have a look at the swf...

This is a pretty nasty implementation of a basic slider. Just felt like writing some obfuscated code today... It could probably be made even more confusing with some additional tweaks...

The other judge for the contest was Rich Shupe. We just reviewed the entries together and have decided on a winner....
The winner is Petri Leskinen (piXelero)
Have a look at the winning snippet if you haven't seen it already.
Rich and I thought that Kyle Phillips deserved honorable mention for his google analytics snippet.
Thanks to everyone who sent in snippets. Even though there were only a handful of submissions I had a good deal of fun reviewing and judging. I still have two more entries that I have yet to publish... so stay tuned...
